DRIVING TEST 2

●

Did any malfunction occur when the proper test in the following test patterns is performed?

●

Test pattern
Driving test finds the difference between the symptoms monitored with and without each sensor.

–

Test pattern 1: Test method with no GPS location correction
Disconnect the GPS antenna connector (GT5) connected to the AV and NAVI control unit. Accurately
adjust the current position and the direction, then drive the vehicle.

–

Test pattern 2: Test method with no map-matching
Accurately adjust the current position and the direction. Eject the map DVD-ROM from the AV and NAVI
control unit with the ignition switch turned to OFF, then drive the vehicle. After driving, insert the map
DVD-ROM back in the unit, display the track of the vehicle on the map screen and compare it with the
actual road configuration.

●

Sample tests

–

<To determine if the current-location mark skips at the same position, if so, whether it is caused by map-
matching or by GPS>
Perform test pattern 1.

–

<To determine if the pattern of streets displayed is correct or not>
Perform test pattern 1&2.
Compare the track of the vehicle on the map screen and the actual road configuration. For fairly accurate
tracking, plotting shall be made every several hundred meters.

–

<When the distance is adjusted accurately>
Perform test pattern 1&2.
Drive on a road of which distance is accurately known (by utilizing distance posts on a highway). Calculate
the rate of change (increased/decreased) of the distance by comparing with the actual distance.
Correction = A/B
A: Distance shown on the screen
B: Actual distance

YES or NO

YES

>>

●

If adjustment is insufficient, perform adjustment again.

●

If any error is found in the map, please let us know.

●

Replace AV and NAVI control unit.

NO

ted or the system has been used on another vehi-
cle.

Drive the vehicle for a while [for approx. 30
minutes at approx. 30 km/h (19MPH)] and
